Abstract
A measured dose dropper includes an adjustable extension fitted within a hollow barrel in an end opposite that of the opening of the barrel. The adjustable extension includes gradation marks which correspond to the volume within the hollow barrel as adjusted by sliding the adjustable extension. A float within the hollow barrel acts as a float valve when fluid is drawn into the hollow barrel, preventing no more than the desired precise amount of fluid to be contained within the hollow barrel. Accordingly, an adjustable measured dose of fluid can be reliably and accurately dispensed.
